Torrasque:I was being sarcastic in my comment. Obviously AI won't be stumbled upon in Minecraft, but it'd be funny if it was. Hence: sarcasm.This guy made a computer in Minecraft just to prove that he could, and probably because he felt like it. Its like the guy that made the Starship Enterprise. Does that accomplish anything? Of course not, but its fun and cool.And judging by what he has said, he didn't really follow that many instructions because alot of his computer is unique and uncommon.I'd say making a computer in Minecraft (even if it is just "following basic instructions") is much more difficult than Gran Turismo. Driving games are easy shit.

...You can't stumble upon AI...That's not how it works...Why is it fun? It's mindless repetition.Why is it cool? It obviously can be done and merely requires a rediculous amount of time. If you think it's cool then clearly you must thing digging 1 billion 15cm holes is cool as it is the same - mindless repetition. What he did is extremely simplitic in terms of electronics. It is far, far simplier than you give it credit for. And saying driving games are "easy as shit" shows you clearly have played very, very few.

lol, you're still missing my point, so I'll say this as simple as I can.AI is hard to get.It won't be obtained in Minecraft.It would be humorous if it was obtained in Minecraft.Hope that makes sense.

Minecraft is fun because its a limitless sandbox game that only has 1 limitation: your imagination. If you don't enjoy it, then its not the game's fault.Of course its simple in electronic terms, its a fucking video game. I think its cool that he made it despite his simple tools and materials, just like I'd be impressed at a man making a computer out of a few chunks of wood and some dead squirrels.

How to play a driving game:Gas is here, turn is here, e-brake is there.Get comfortable with how to drift, get familiar with levels.Voila. Driving game mastery 101.

*so you don't miss my point again*That was not sarcasm.I am not saying driving games are hard.I am saying driving games are easy.

1) You don't "get" AI. That's like saying you "get" a Ferrari by digging in the Sahara. 2i) Minecraft is far from limitless. You make very limited buildings that usually serve no purpose and can't even move. 2ii) Therefore the limit is not the imagination, it's the extremely basic and limited mechanics of Minecraft3) The computer analogy makes no sense. You are essentially comparing following basic instructions to magic. 4) Congratulations, you clearly have never played, or been good at, any racing game you've played.

There's basically a Dwarf Fortress version of everything you can do in Minecraft, except instead of falling to your death from the top of some wires, an artist can't find a turtle shell and precipitates a murder cascade as survivors are picked off by wild mandrills. Okay that does happen, but only in multiplayer.

"Another thing that I've done, but I don't know if it's unique, is that my buses are verticle. This means that they are only 1 block wide, but it does make my cpu very high," Salaja said. "I died many times by falling from the top."

I think the amount of horizontal and virtical space necessary to reproduce a modern computer would easily dwarf the computer running Minecraft's ability to render it. Simply put, trying to play Minecraft on Minecraft would easily crash the original computer. Or at the very least it would take hours for the signal to get around via redstone, just to jump once.

This comment thread was pretty sad.. Doesn't anyone have the ability to read previous comments before adding their own anymore? I thought that was pretty standard etiquette, but I guess it's just the places I usually hang.

Anyway, for the people saying that it's not impressive because any comp sci major understands how it works: Well big duh. I can agree that the knowledge behind it is indeed rather trivial - for those who us who are already educated in the subject. But I might as well say that solving a Rubik's cube is trivial for anyone who is really good at it. It's true, but why would it matter in any discussion about a person who is not a Rubik's cube expert?

By his own statement the guy didn't know exactly how a CPU works when he started doing this project. He learned that while doing it. So besides the thing taking some Minecraft-skill to put together (it's much easier handling physical components and getting an overview in the real world than trying to see in Minecraft how everything fits together with redstone) he learned some really important digital electronics through this. Both of those things are an accomplishment to do by yourself.

Actually, as far as I can tell from the explanation given by the gentleman who built the thing, this system does not have anything that would qualify as RAM, merely registers. Also, for the record, this device (while impressive) does not really qualify as a "CPU". It has a series of registers (which store data, either catching the result of an operation or holding information being operated upon) and an ALU (arithmetic logic unit. Basically a mass of resistors that perform simple arithmetic operations on two input values) but is lacking an FSM (finite state machine - a device that determines what operation is being performed by the hardware). What's more, it more or less lacks an operations register (the register that sends data to the FSM so that the FSM knows what state to choose). Both of these tasks are present but they are performed by the user.

Now, I'm quite sure such a thing could be implemented (if you can build a register you can build an operations register. And if you can build a register you can build RAM and store an extensive list of operations. With the things displayed here a universal turning machine could indeed be constructed), certain things, like a robust FSM or a seemingly large (say a 100 address word addressable RAM space) would require an enormous amount of physical space within the game and would easily dwarf those things already present in terms of complexity.

So, BRAVO to the man who created this but there is still a lot of room to grow before we have something that truly resembles what we call a computer.

In light of this I think I just lost any ambition to play minecraft. I mean while im puttering around my piddly little cobblestone fort, people are programing the game to play minecraft IN minecraft and crafting a virtual computer. I am overwhelmed with a resounding "Whats the point?"
